In my previous article http://ranjeetbadhe.com/tripleo-undercloud I discussed the Undercloud testbed setup and the installation steps. I hope you have to work Undercloud and we can start the overcloud deployment. In my testbed, I have got 1 Director node,1 Compute node and 1 Controller node. These nodes are virtualized on ESXi Hypervisor. The below screenshots shows the configuration of these 2 VM’s. For the 3 nodes, I have allocated 24GB memory to…
